Oh yes I noticed that. I guess the 32MB headroom is not enough with a high res display …

SqueakJS artificially limits the amount of memory used, like old Squeak VMs used to do, partly because there’s no way to query the actual available memory size via JavaScript.

Not sure what the best way is to deal with that. Maybe if we run out of room we should do a full GC, and if that didn’t help, increase the headroom?

Thank you Vanessa!

If I open Marcel's link https://squeak.js.org/run/#zip=https://files.squeak.org/6.0/Squeak6.0-22104-... on my high-dpi device (250%), it loads about one minute and then reproducibly says:

But I have more than 1 GB free RAM. If open the link on a low-DPI screen instead, and move it to the other screen afterward, everything works fine. :-)

Best,

We only had to recognize the new image format – sorry it took me so long. Thank you, Christoph Tiede and Dave Lewis! (https://github.com/codefrau/SqueakJS/pull/138)

TODO: actually implement primitive 578 (but then, quite a few non-essential prims are still missing)

Enjoy! Vanessa
